XML 配置文件註釋引起錯誤及解決方案

在配置war/src/webroot/META-INF/autoconf/news-resource.xml.vm時，在xml文件中有中文的註釋。重新編譯後啓動時，產生下列的異常

從錯誤描述來看發現是ＸＭＬ文件中的註釋引起的異常，去掉配置文件中的中文註釋或改用英文描述則可以通過
後來發現是配置文件中採用：

單數箇中文或字母后跟單數箇中文再用“-->”結束註釋（中文後不加空格） 
如：<!-- 單數箇中文-->、<!-- a單數箇中文--> 

時就會報此異常
爭對此異常可以採用在左右邊界加上空格的方式解決。
在Eclipse中開發時不太容易出現此異常，因爲Eclipse的XML　格式化功能會自動在書寫時加上空格，但如果用netbeans
開發時則要注意此項自己手動加上空格。
